Abstract: A method and system of automatic redundant array of independent disks (RAID) volume generation based on an application type is disclosed. In one embodiment, a method for selecting a RAID level includes receiving setup data of an application type and a number of volumes for generating the RAID, assigning a level of the RAID in response to the application type and generating the number of volumes for the level of the RAID. The method may also include mapping the number of volumes to a host of the RAID, scanning the volumes for data written to the volumes and read from the volumes and evaluating the data to determine an appropriateness of the level of the RAID for the application type. Further, the method may include automatically migrating to another RAID level for the application if the level of the RAID is inappropriate.

Abstract: Hierarchical storage management (HSM) for redundant array of independent disks (RAID) which comprise a plurality of drive trays of different types is disclosed. In one embodiment, a method for hierarchically managing RAID which includes a plurality of drive trays of different types, includes writing data to a tray of a first type, periodically monitoring a use of the data, and moving the data to a tray of a second type if the use of the data yields less than a threshold value. Each one of the tray of the first type and the tray of the second type includes at least one hard drive, and a composite score of price, capacity, performance, and function of the tray of the first type which is higher than a corresponding composite score of the tray of the second type.
